Abstract: CHILD RESISTANT PACKAGE Abstract of the Disclosure A child resistant package comprising an open-mouth container having a plurality of circumferentially spaced projections extending radially outwardly adjacent the open end thereof, each projection defines a notch facing downwardly, and a closure having a top panel and an annular skirt depending from the periphery of the top panel, and a plurality of radially inwardly extending and circumferentially spaced locking lugs on the inner surface of the skirt.  The locking lugs are adapted to engage the notches in the projections on the container.  A tamper-indicating member comprises an annular ring having portions extending between the lower edge of the skirt of the closure and a portion of the container and operable to normally limit axial movement of the closure.  The ring offers a visual indication that the contents have not been tampered with and the ring must be removed before the closure can be removed.  The container includes a specially designed inclined surface provided with dual slopes.  One slope extends radially outwardly in a circumferential direction and the other slope extends downwardly and radially inwardly and terminates in a locking notch.  The closure can be applied to the container when the tamper-indicating member is in position through rotation of the closure causing the cam lugs on the closure to engage the inclined surface and flex the skirt of the closure outwardly to thereby direct the cam lugs over the shoulder and into engagement with the locking notch.

Abstract: - Abstract of the Disclosure -A new process for the preparation of 6-deoxyanthracyclinones of general formula I;                 I     wherein R represents a hydrogen atom, a hydroxy group or a lower alkoxy group is described. The  process provides a total synthesis of the 6-deoxyanthracyclinones of formula I using a 1,2,3,6-tetrahydro-phthalate as starting material.          The obtained racemic mixture of the compounds of formula I, if desired, can be submitted  to optical resolution by the conventional method of  conversion to diastereomeric deri-vatives using  a chiral resolving agent. Alternatively, the racemic mixture can be used as such for the condensation with a suitably protected halosugar derivative to obtain alpha glycosidic derivatives of formula XV:            XV   wherein R1 represents a hydrogen atom or a hydroxy group, one of R2 and R3 represents a hydrogen atom, the other of R2 and R3 represents a hydrogen atom or a hydroxy group and X is a hydrogen atom or a trifluoro acetyl group.  The N-trifluoroacetyl 7S:9S and 7R:9R deri vatives of the ?-glycosides of formula XV can be separa ted by chromatography on silica gel to obtain, after mild alkaline hydrolisis the wanted  7S:9S  ?-glycosides (R1=H) as free hases and can eventually be transformed-into their corresponcling doxorubicin  derivatives (R1=OH) by known procedures.  These .alpha.-glycoside deriva-tives have anti-tumour properties.

Abstract: Abstract:            Method and device for measuring the distance to an object, particularly the distance to the surface (17) of a liquid in a container (15). An antenna (11) is arranged in a distance from and aimed against the sur-face, the antenna being connected to a measuring unit (12), a channel unit (13) and a control unit (14). A microwave signal with a predetermined frequency is gene-rated in the measuring unit (12), of which a part is utilized as a reference signal, while a further part is input to the antenna (11) and transmitted against the surface (17). From the reflected signal received by the antenna and supplied to the measuring unit (12) and the reference signal, a function of the antenna input reflec-tion coefficient is formed. This function is adapted to the current condition. A fourier transformation of a set of values of this function at a certain set of measuring frequencies is made, from which the distance to the sur-face is calculated.            Fig. 1.

Abstract: MULTI-LAYER THIN FILM, FLEXIBLE SILICON        ALLOY PHOTOVOLTAIC CELL                             ABSTRACT      The flexible photovoltaic cell includes thin front and rear junction regions electrically in series each formed of ceramic metallic glass semi-conductor alloys of silicon of approximately zero thermal expansion/ contraction coefficient laminated with an interveninq semi-conducting layer less than 60 Angstroms thick or an insulating layer less than 20 Angstroms thick.  The respective spectral sensitivities of front and rear junction regions are tailored to different frequency ranges. In front are six layers described in sequence rear to front.  The lowermost (sixth) is a green/blue semi-insulating cobalt and tin passivating and filter layer less than 10 Angstroms thick.  The fifth is a semi-conductive, degradation-protective "window" and one-way mirror for returning back-reflected light.  The fourth is an insulating tunneling layer less than 15 Angstroms thick for coupling a front collection grid to the "window".  Covering the fourth is a triple-layer, anti-reflection coating (ARC) whose middle layer bonds the outer ARC layers and secondarily protects the cell from atmospheric degradation.  An internally reflective rear ARC layer cooperates with the "window" for return-ing back reflected light.  The frontmost ARC layer is mainly comprised of Al2O3/SiO2 in the range of 200 to 650 Angstroms thickness.  The cell backside is shown having undulations for randomizing reflected light rays. The six front layers effectively adapt the cell for receptivity to solar radiation from about 4,000 to about 12,000 Angstroms, excluding radiation outside thereof, thus accepting 68 percent of solar energy vertically reaching the earth's surface.

The multiplication layer is then mesa-etched and another semiconductor layer is second grown on the mesa-etched multiplication layer.  A dopant having a conductivity opposite to that of the above layers is introduced from the top of the another semiconductor layer to form a doped region extending inside the mesa portion and a p-n junction is therefore formed inside the mesa-etched portion.  This causes the distribution of multiplication in the active area to become uniform, since the rough surface of the top of the mesa-etched portion exists outside the multiplication region.

Abstract: IMPROVED APPARATUS FOR STOPPING A GRINDING MILL           ABSTRACT OF THE DISCLOSURE In a system having a large load driven by at least one electric motor through a clutch, when the system is to be stopped, the power is removed from the motor and the clutch opened or released.  The motor and load will continue to move until stopped by friction and it is desirable to stop them more quickly.  When the motor is freely rotating and the load oscillating, as in a grinding mill, the clutch may be pulsed at spaced intervals of time for a short duration to a level where the clutch is partly closed and this will slow both the motor and load. Alternately the motor may be electrically braked by placing a low resistance across the rotor windings and applying DC to the stator windings of the motor.  When the motor is stopped it can be used to brake the load by locking the motor with an application of DC to the rotor and stator windings and periodically pulsing the clutch to partly close the clutch for short durations of time.  In accordance with the invention the motor is not locked during the pulsing of the clutch but is caused to rotate very slowly in order to cause the slip rings carrying DC power to the rotor to rotate beneath the associated brushes to prevent generation of heat in a localized area beneath the brush.

Abstract: Abstract of the Disclosure In case where a surface active agent is contained in waste water, it is extremely difficult to remove the surface active agent, and the present invention has previously found that the surface active agent is oriented and adsorbed in the periphery of colloidal particles, by making use of the fact that an association property exhibits when a concentration exceeds a micel concentration, whereby the periphery of the particles are partly made to increase the concentration to a level above the micel concentration to adsorb and remove the surface active agent in the waste water.  The treating agent for that purpose is produced by emulsifying oil, montmorillonite and the like and adsorbing soda of fatty acid or potash salt thereto.

Abstract: ABSTRACT     A hand movement controller is described which permits a variety of control functions to be performed by single left or right handed operation.  The controller comprises a base which is generally wedge-shaped with a sloping surface on which is located a movable palm support adapted to be received in the palm of a hand when the hand rests on a sloping surface.  A plurality of keys are symmetrically spaced about the palm support and adapted to be engaged by fingers of the hand.  The distance between the movable palm support and keys is adjustable to support the fingers to permit them to pivot freely about the knuckles with minimal strain over a prolongued period of time.          The spacing of the keys about the palm support is designed to optimize reaction time and to take full advantage of normal reactions for both left and right handed individuals.  In a preferred embodiment eight keys are used and permit control of movement in three dimensions as well as two dimensions, an actuation of control means in an object at a predetermined position in two dimensions as well as the three dimensions at a predetermined point and space.  The upper surface can be moulded from a plastic thermoplastic material to be custom suited to the individual and the controller is particularly suitable to handicapped persons.

Abstract: ABSTRACT OF THE DISCLOSURE     A hard surface cleaning composition forming upon agitation a relatively unstable emulsion breakable when applied to the hard surface to be cleaned comprising on a weight basis from about 2 to about 10% of an organic polar solvent; from about 0.1 to about 2.0% of a volatile organosiloxane;  from about 0.1 to about 2.0% of a volatile surfactant having the formula:       wherein R1 is an alkynyl of from two to five car-bons; R2 is hydrogen or an alkyl of less than four carbons, and R3 is an alkyl or hydroxy alkyl of from one to eight carbons, the total number of carbons being from four to twelve, and water, the ratio of said volatile surfactant to said volatile organosiloxane being between about 3:1 to about 1:3.          The preferred volatile surfactant is 3,5-dimethyl-1-hexyn-3-ol, while the preferred siloxane is the dimethyl siloxane cyclic tetramer.          Preferably, the polar solvent is a solvent system comprising a low boiling solvent and a high boiling solvent.  Optional constituents include builder salts, alkalinity agents, dye and perfume.  After shaking, the emulsion formed is applied to the surface and wiped with a cloth, paper towel or sponge.  The breaking of the emulsion and the eva-poration of the volatile constituents is demonstrated by a bubbling action that is believed to assist in the cleaning of the surface.
